Description
Technical Field
The invention belongs to the technical field of experimental equipment, and particularly relates to a remote-control large-batch sample point source irradiation rack and an irradiation laboratory comprising the same.
Background
The role of ionizing radiation in human production and life is more and more obvious, and the potential harm to people is more and more widely taken as a double-edged sword. The radiobiological research is the foundation for promoting the radiation protection, and the research result has important theoretical significance and application value in the formulation of radiation protection limit values and the evaluation of radiation protection effect. In such studies, the radiobiological effect is closely related to factors such as the type of radiation, the location, the dose rate, and the surrounding material environment of the irradiation model. In a specific experiment process, cell strains, nematodes, experimental animals and the like are often selected as research objects.
Neutrons play a core role in a variety of nuclear facilities, such as reactors. The neutral charge of the material has high penetrability, and is easy to cause various secondary nuclear reactions, generate charged particles and form recoil ions to cause serious biological injury effect. Therefore, the influence of neutron radiation on human health is receiving more and more attention, and the development of neutron radiation protection research is an important issue in the industry. However, the worldwide research on neutron radiation effect and mechanism is relatively small, and the main reason is that: one is that neutron sources capable of producing sufficient flux are scarce and neutron radiation fields are precious. In order to fully utilize the space of a radiation field and ensure that each treatment group reaches a preset dose, distance measurement and sample placement are required to be carried out at least 1 hour in advance in the conventional neutron animal and cell radiation experiment process; because the number of samples is too many and the measurement precision is limited, the irradiation dose of each batch of samples is difficult to realize to be consistent. Secondly, due to the influence of residual rays of induced radioactivity, materials cannot be taken immediately after radiation to conduct experimental exploration in a short time. In a high-energy neutron radiation experiment, high-energy neutrons ionize substances such as air, earth and materials in a field, induced radioactivity is caused, and the field can reach an allowable dose rate level only after at least 1 hour of air exhaust and noise reduction (noise reduction time is determined according to different doses), so that the key research on biological effects and mechanisms in a short time after comparison is severely limited.
How to enable a large batch of samples to be irradiated accurately with enough dosage in the neutron animal and cell radiation experiment process and realize that the samples can leave a radiation source quickly after irradiation, is a problem to be solved urgently in neutron radiation biological effect and biological protection experiments.
